My Yeasu Ft-2800M emits an annoying tone burst every time I key the mike. It is heard by both the sender (me) and the receiver(s). I cannot find any reference in the manual except for the 1750 Hz tone burst that can be generated by one of the P-buttons on the mike. The tone that I want to get rid of, is actually somewhat lower in audio frequency that this. I purchased the rig used, with all the local frequencies entered, so I do not want to do a reset and lose all that.Can anyone tell me how to get rid of this tone?

I don't know what to say, this has never happened before in the vhf/uhf forum...it looks like you may be the first person to ever come back and tell us how thingsturned out! Thank you for the Thank you!
